A MillionVerifier alternative that resolves catch-all
MillionVerifier is $449 per million and does not bill catch-all results. It also does not resolve them. We do, which changes how much of a list you can actually use.
Bottom line
- Catch-all
- We confirm it, valid or invalid. MillionVerifier marks most Risky (5% resolved, the lowest in the LeadMagic test).
- Real cost
- Price per usable contact, not per credit. An address you paid to check but cannot email still cost you.
- At 1M
- $449 vs $680. What each returns on catch-all decides the cost per usable contact.
- Try it
- 1,000 free credits on a bulk list, no card.
How Giggal.ai verifies catch-all addresses
MillionVerifier is fast on ordinary domains. On a catch-all domain it marks the address risky, does not charge you, and moves on. Fair billing, but the address is still unusable. We route those addresses down a separate path and return one of four results.
| Result | Meaning |
|---|---|
| Deliverable | The mailbox exists and will accept mail |
| Undeliverable | The mailbox does not exist |
| Risky | The address exists but carries deliverability risk |
| Unknown | We could not verify the address, and the credit is refunded |
Figures for MillionVerifier come from an independent test run by LeadMagic, published 25 February 2026, on 10,000 real B2B emails, 28% of them on catch-all domains.
This test was published by LeadMagic, which sells a competing email verifier and ranked itself first in its own results. Read it as a vendor test, not a neutral study. Giggal.ai was not one of the tools measured in it.
Per credit vs per usable contact
Say a list is 30% catch-all. Run it through a tool that marks catch-all Risky and a third of what you paid to verify comes back unusable. The real cost is the price per credit divided by the share of the list you can send to. A credit that returns only a flag can cost more per usable contact than one that returns a real answer.

Frequently asked questions
At a million, MillionVerifier is $449 and Giggal.ai is $680. The number that matters is price per usable contact, because the two hand back different things on catch-all addresses, and a flagged address is one you cannot email.
It tells you whether the mailbox is real, deliverable or undeliverable. MillionVerifier marks them Risky and does not confirm the mailbox, 5% resolved in the LeadMagic test, the lowest measured. Catch-all is 1.5 credits in a run, 2 standalone.
No, and that is fair. It does not charge for risky results, which covers unknown and catch-all. You still end up with a segment you cannot email, only un-billed.
A confirmed catch-all is a contact you can email. One that was only flagged is not, even if you were not charged for it.
Yes. 1,000 free credits, no card, on a bulk upload. Run a catch-all-heavy list and see how much comes back usable rather than merely un-billed.
